When a number is multiplied by itself thrice, the resultant number is called the cube of a number. Cubing is used while comparing sizes of objects or things with cubic measurements. In this topic, we shall learn about cubes of 798.

Cube of 798

A cube number is a value obtained by raising a number to the power of 3, or by multiplying the number by itself three times. When you cube a positive number, the result is always positive. When you cube a negative number, the result is always negative. This is because a negative number by itself three times results in a negative number.

The cube of 798 can be written as 798³, which is the exponential form. Or it can also be written in arithmetic form as, 798 × 798 × 798.

How to Calculate the Value of Cube of 798

In order to check whether a number is a cube number or not, we can use the following three methods, such as multiplication method, a factor formula (a³), or by using a calculator. These three methods will help kids to cube the numbers faster and easier without feeling confused or stuck while evaluating the answers.

  1. By Multiplication Method
  2. Using a Formula
  3. Using a Calculator

By Multiplication Method

The multiplication method is a process in mathematics used to find the product of two numbers or quantities by combining them through repeated addition. It is a fundamental operation that forms the basis for more complex mathematical concepts.

Step 1: Write down the cube of the given number. 798³ = 798 × 798 × 798

Step 2: You get 508,373,352 as the answer. Hence, the cube of 798 is 508,373,352.

Using a Formula (a³)

The formula (a + b)³ is a binomial formula for finding the cube of a number. The formula is expanded as a³ + 3a²b + 3ab² + b³.

Step 1: Split the number 798 into two parts, as and . Let a = 700 and b = 98, so a + b = 798

Step 2: Now, apply the formula (a + b)³ = a³ + 3a²b + 3ab² + b³

Step 3: Calculate each term

a³ = 700³

3a²b = 3 × 700² × 98

3ab² = 3 × 700 × 98²

b³ = 98³

Step 4: Add all the terms together:

(a + b)³ = a³ + 3a²b + 3ab² + b³

(700 + 98)³ = 700³ + 3 × 700² × 98 + 3 × 700 × 98² + 98³

798³ = 343,000,000 + 144,060,000 + 20,402,400 + 941,952

798³ = 508,373,352

Step 5: Hence, the cube of 798 is 508,373,352.

Using a Calculator

To find the cube of 798 using a calculator, input the number 798 and use the cube function (if available) or multiply 798 × 798 × 798. This operation calculates the value of 798³, resulting in 508,373,352. It’s a quick way to determine the cube without manual computation.

Step 1: Ensure the calculator is functioning properly.

Step 2: Press 7 followed by 9 and 8

Step 3: If the calculator has a cube function, press it to calculate 798³.

Step 4: If there is no cube function on the calculator, simply multiply 798 three times manually.

Step 5: The calculator will display 508,373,352.

Tips and Tricks for the Cube of 798

  • The product of two or more perfect cube numbers is always a perfect cube.
  • A perfect cube can always be expressed as the product of three identical groups of equal prime factors.

Common Mistakes to Avoid When Calculating the Cube of 798

There are some typical errors that kids might make during the process of cubing a number. Let us take a look at five of the major mistakes that kids might make:

Problem 1

What is the cube and cube root of 798?

Okay, lets begin

The cube of 798 is 508,373,352 and the cube root of 798 is approximately 9.283.

Explanation

First, let’s find the cube of 798.

We know that cube of a number, such that x³ = y Where x is the given number, and y is the cubed value of that number

So, we get 798³ = 508,373,352

Next, we must find the cube root of 798 We know that cube root of a number ‘x,’ such that ∛x = y Where ‘x’ is the given number, and 'y' is the cube root value of the number

So, we get ∛798 ≈ 9.283

Hence the cube of 798 is 508,373,352 and the cube root of 798 is approximately 9.283.

Problem 2

If the side length of the cube is 798 cm, what is the volume?

Okay, lets begin

The volume is 508,373,352 cm³.

Explanation

Use the volume formula for a cube V = Side³.

Substitute 798 for the side length: V = 798³ = 508,373,352 cm³.

Problem 3

How much larger is 798³ than 700³?

Okay, lets begin

798³ – 700³ = 165,373,352.

Explanation

First find the cube of 798, that is 508,373,352

Next, find the cube of 700, which is 343,000,000

Now, find the difference between them using the subtraction method. 508,373,352 – 343,000,000 = 165,373,352

Therefore, the 798³ is 165,373,352 larger than 700³.

Problem 4

If a cube with a side length of 798 cm is compared to a cube with a side length of 500 cm, how much larger is the volume of the larger cube?

Okay, lets begin

The volume of the cube with a side length of 798 cm is 508,373,352 cm³.

Explanation

To find its volume, we multiply the side length by itself three times (since it’s a 3-dimensional object).

Cubing 798 means multiplying 798 by itself three times: 798 × 798 = 636,804, and then 636,804 × 798 = 508,373,352.

The unit of volume is cubic centimeters (cm³), because we are calculating the space inside the cube.

Therefore, the volume of the cube is 508,373,352 cm³.
